Carbon dioxide-<SUP>12</SUP>C CAS 124-38-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 44.00 g/mol gives Carbon dioxide-<SUP>12</SUP>C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Carbon dioxide-<SUP>12</SUP>C (CAS 124-38-9), molecular formula [12C]O2 and molecular weight 44.00 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula [12C]O2, Carbon dioxide-<SUP>12</SUP>C contains an organic framework; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 44.00 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
